Answer:
Job A, will take 24 hours and Job B, will take 30 hours
Step-by-step explanation:
12 X 30 = 360 and 15 X 24 = 360
3.7cm on the map represents 1850km in reality
3.7cm : 1850km
1cm : 1850/3.7 km
1cm : 500km
Scale statement for map is : 1cm : 500km.
That is 1cm on map represents 500km.
1cm : 500km. Recall 1km = 1000m = 100 000cm
1cm : 500* 100000cm
1cm : 50 000 000cm
1: 50 000 000.
Scale factor is 50 000 000.
